The wireless mobile ad-hoc network (MANET) is set of dissimilar types of mobile nodes. These nodes in MANET communicate with each other without any fixed infrastructure. Because of MANET’s infrastructure network is unprotected from the attacks of malicious nodes. One of the attacks is called black hole attack. In MANET black hole attack is occurring easily. In the black hole attack node falsie advertises that they have secure path to destination and absorb the data packet. Nodes those drop or misuse the data are called malicious nodes. This paper focus to analyzed the performance of reactive (AODV), proactive (OLSR) and hybrid (ZRP) routing protocols with blackhole attack and without blackhole attack using different performance metrics like Packet Delivery Ratio, Average Jitter, Average Throughput and Average End to End Delay. The simulation study of ad-hoc routing protocols in MANET is done with Qualnet5.1 simulator.
